DISPENSING MECHANISM FOR SYRUPS.

ecaece.

To all whom it may concern:

Be it known that I, LOUIS A. BECKER, a citizen of the United States,residing at Chicagofin the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Dispensing Mechanism forSyrups, of which I do declare the following to be a full, clear, andexact description, reference being had to the drawing forming part ofthis specification.

My present invention has relation more particularly to the improvementof dispens ing apparatus such as is used for withdrawing from the syrupjars of soda water fountains a measured quantity of syrup and the objectof the invention is to provide a simple, cheap, effective and durableconstruction of dispensing apparatus.

To this end the invention consists in the features of improvementhereinafter described, illustrated in the accompanying drawing andparticularly pointed out in the claims at the end of this specification.

Figure 1 is a view in vertical section through a portion of a soda waterfountain having my invention applied thereto, the mechanism embodying myinvention being shown in elevation. Fig. 2 is a view in cen tralvertical section through my improved dispensing apparatus, the sectionbeing taken on line 2 2 of Fig. l. Fig. 3 is a view in perspectiveshowing upon an enlarged scale the lower portion of my improvedapparatus.

In the accompanying drawing A designates that portion of the soda waterfountain adapted to receive the syrup containing jars,-a portion of oneof said jars being shown and designated as B in the drawing. Preferablythe jar B is provided with a pocket or depression Z2 in its bottom tobetter admit the syrup to the measuring cup of my improved apparatus. Inthe drawing the receptacle A is shown as provided with a downwardlyfolding door A that is hinged at a, this being one simple and familiarform of receptacle.

Through an opening in the top of the chamber A and above the syrup jar BeX- tends the upper portion of my improved dispensing apparatus, and asshown, a plug or bushing a2 may be inserted in the opening at the top ofthe chamber A to better guide the reciprocating movement of thedispensing apparatus.

Specification of Letters Patent.

Application filed October 30, 1905.

Patented J uly 5, 1910.

Serial No. 284,969.

My improved apparatus comprises a tube C having a measuring cup Dconnected at its lower end, and this measuring cup is adapted to receivea piston E that will reciprocate within the cup. A stem E of the pistonE is tubular and leads upward from a central opening in the piston andthrough the tube C to the lower end of which is connested the cap orcover D of the cup D. The upper end of the hollow piston stem E isconnected to the head portion of a discharge spout G through which thesyrup will be discharged into drinking glasses or like receptacles. Asshown, an outer tube I-I extends downwardly from the discharge spout Gat its lower end overlapping in manner free to move, the upper end ofthe tube C. Within the outer tube I-I and encircling the upper portionof the hollow piston stem E, is placed a coiled spring J, the upper endof which bears against the lower portion of the head of the dischargespout Gr, while its lower end bears against the upper end of the tube C.

In the preferred form of my invention the cap or cover D of the cup D,is formed with an interiorly threaded flange d adapted to .iit aroundand engage the correspondingly threaded upper portion of the cup E, sothat the cup may be detacliably connected to its cap. By this means,cups of different sizes may be employed according to the demands of thecustomer and the character of syrup or other fluid that is dispensed. Asshown, the cap or cover D of the cup D is substantially the same ininterior diameter as the cup D, so that the piston E may move freelyfrom the cap or cover D into the cup D and across the threaded jointthat unites the two. The cap or cover D is formed more or less open toadmit the syrup into the cup D beneath the piston E, and this may beaccomplished by employing any desired number of holes or openings Z2 inthe cap or cover D. Preferably, the cap or cover D is attached to thetube C by a screwthreaded joint c that enables these parts to beconveniently formed and to be readily taken apart for cleaning or otherpurposes.

By preference, the upper end of the hollow stem E is attached to thehead of the discharge spout G by a screw-threadedjoint e and bypreference also, the outer tube II is connected to the head of thedischarge spout Gr by a similar threaded joint h. A

port g in the head of the discharge spout Gr connects with the mainchannel g of said spout. As shown, the discharge spout Gr is providedwith a pressure plate Gr whereby the attendant may conveniently depressthe discharge spout Gr, as will presently appear, and preferably thispressure plate G is formed with a threaded stein g2 adapted to setwithin a correspondingly threaded opening in the top of the head portionof the discharge spout G.

From the foregoing description, the operation of my improved dispensingapparatus will be seen to be as follows: lVhen the parts are in thenormal position shown in the drawings, the piston E will be held by thecoiled spring J in the upper portion of the cap or cover D of the cup D,so that syrup or like liquid from the jar B may pass through the openingZ2 into the cup D. If now the discharge spout Gr be forced downward bythe pressure of the hand of the attendant upon the pressure plate Gr',the piston E will move down into the cup D and will force the liquidcontained therein up through the hollow piston stem E and through thedischarge spout Gr into the drinking glass or like receptacle placedbeneath the spout. Then the attendant relieves the pressure of his handfrom the discharge spout G the coiled spring J will restore the parts tothe normal position shown in the drawing. It will thus be seen that eachtime the attendant depresses the discharge spout of the apparatus, ameasured quantity of syrup or like liquid will be delivered through thedischarge spout.

It should be noted that -the improved dispensing device is in no waydependent upon any support at its upper end. 1t is only necessary thatthe dispensing device rest upon the bottom of the receptacle containingthe liquid to be delivered. The operating-spring J serves to hold thepiston within the upper end of the dispensing cup against its cap and isprotected from contact with the liquid in the jar by the tube or sleeveH. The dispensing device consists of few parts which may be readilydetached from one another for cleaning. By having a closed bottom to thedispensing cup D with inlet openings at its upper end above which thepiston E is normally held, it is not necessary to provide valves of anvsort in the device. This is quite an advantage since such valves readilydeteriorate, leak and wear out.
